If Keene's mother was living in the city, she may well have had him buried in some other cemetery. By the map, it appears that Hollywood is closer to where she may have lived on 11th St. near Franklin.

See a map of the city here. Oakwood was located to the north off 31st St.
Castle Thunder is number 53, on the north side of Cary St., between 18th & 19th Streets.
